Description

Field

The invention relates to children's construction kits for assembling building toys with the use of connecting elements.

Background of the invention

In the background of the invention, there is a known multi-model toy construction kit (Patent RU 104081 , Int.Cl.: A63H33/10, publ. 10/05/2011), that contains connecting elements and a set of structural parts with through-holes which are placed in 1-3 rows alongside the structural part, wherein several holes have the same diameter and are placed in a row and along the round surface of the discs, except the central hole of the discs, plain washers, in which the diameter is smaller. The thickness of the discs is 5-10 times bigger than in all structural parts, and in the angle pieces the holes are oval on one side, and the distance from the centers of the holes to the folding line is twice as long as the distance from the centers of the holes to the ends of the angle pieces, wherein the edges of the angle pieces are rounded.
The hard, static form of the parts of the said construction kit does not enable to transform its linear dimensions, change the volume and proportions, which considerably limits the amount of possible variants of assembled models. Also, a great amount of bolted and core connecting elements increases labor input and the difficulty of the assembling of the models, as well as a risk for a child to be injured while playing.
Known in the prior art a construction kit of a soft toy (Certificate of utility model RU 2195, Int.Cl.: A63H3/02, publ. 16/06/1996), that consists of a body frame and component parts attached to the body frame or to each other by means of fixation devices, wherein some of the mentioned fixation devices are designed as pairs of separable connecting pieces, one of which is attached to one component part, while the other is attached to another component part or the body frame; and also at least one extra component part and/or at least one extra body frame with fixation devices attached.
The major unsatisfactory features of the above mentioned construction kit are the following: a minimum amount of the assembled models, negative stability of the assembled toys, inability to fix the changed form of the modular elements.
As the prototype, the given construction kit of a soft toy was chosen (Patent RU 2448754 , Int.Cl.: A63H33/04, publ. 27/04/2012), which comprises a set of modular elements with tools to connect elements to each other which are made of cloth or some other elastic material in the form of geometric shapes or forms with fastening elements attached to their surface. These fastening elements can temporary hold the connecting points together or portions of the surface of the modular elements, wherein the fastening elements are selected and placed on the surface of each modular element in such a way that the original shape of the modular element can be reversibly changed, subjected to transformation by bending, folding, twisting or turning. The reshaped modular element is fixed by fastening elements.
Unsatisfactory features of the given construction kit are:

Low reliability of fixation of one-side fastening elements to the surface of a modular element. As a result of frequent connection and disconnection manipulations with the construction kit, the mating surface of the modular element gets gradually destroyed, which causes early separation of the fastening element.
Inability to assemble models and constructions with dynamic characteristics, which decreases the amount of possible game manipulations with the assembled model.
Inability to create a steady and spatial construction out of modular elements. The attempt to form a steady spatial construction will lead to the strain break of the form due to the gravity force of the weight of the construction.

Disclosure of technical invention

The technical result achieved at the use of the claimed building toy extends functional capabilities of the similar construction kits that provide the possibility of assembling both simple models and complex spatial constructions with dynamic properties, highly stable geometric parameters at heavy loads and high reliability of fixation of the fastening elements on the surface of the modular element.
To achieve the above mentioned technical result the building toy is offered, which consists of a set of flat shape-forming and decorative modular elements of flexible resilient material in the shape of geometrical figures or forms with fastening elements attached to the surface that make detachable joints capable to hold connected portions of the surfaces together, wherein the fastening elements are placed on the surface at the minimum of some part of shape-forming modular elements in such a way that the original form of such modular element can be reversibly changed with the following fixation of the changed forms by the above mentioned fastening elements. Wherein according to the suggested technical invention each of the fastening elements takes the form of the center of axial rotation at the minimum of the held portion of the surface of the connected modular element, where each of the shape-forming modular elements on its opposite surfaces has at least one coaxial pair of fastening elements rigidly interconnected and has oppositely oriented mating surfaces which forms a double-side fixation tool.
The realization of the fastening element in the form of the center of axial rotation of the held portion of the connected modular element ensures the dynamic characteristics of the assembled models, for example, the possibility of angular rotation of animals' limbs.
The realization of each of the shape-forming modular elements which has at least one coaxial pair of fastening elements on its opposite surfaces, rigidly interconnected and have oppositely oriented mating surfaces which form double-side fixation tool, wherein the coaxial pair ensures high reliability of fixation of fastening elements on the surface of the modular element. Wherein, stiff connection of coaxial fastening elements increases stiffness and frontal stability of multilayered forms under own weight that enables heavy pressure manipulations with the model in the game process.
The coaxial position of the fastening elements ensures the capability of building up multilayered forms with identical or single-type flexible modular elements without longitudinal and transversal displacements of the connected surfaces, which expands options of the construction kit. Stiff connection of coaxial fastening elements increases stiffness and frontal stability of multilayered forms under own weight that enables heavy pressure manipulations on the surface of the model during the game process.
Wherein, the fastening element of the modular element can be performed as the center of axial rotation of the part of the surface of the connected modular element or the center of axial rotation of the entire surface of the connected modular element, for example, propulsive units (wheels, propellers etc.)
Wherein, the fastening elements that form detachable joint can be embodied either as inner metal and outer magnetic mating fastening elements or the inner fastening element which has the form of the projection which widens at the end of the revolving surface and the outer fastening element provides the surface with full or partial elastic coverage of the projection of the inner fastening element. These detachable joints ensure reliable fixation and capability of axial rotation of connected portions of modular elements.
Wherein, depending on the requirements to the modular element, a double-side fixation tool can consist of outer and inner fastening elements, either a pair of outer fastening elements, or a pair of inner fastening elements.
Wherein, fastening elements of the double-side fixation tools can be rigidly connected to each other at the bearing surfaces by the connecting central core made of solid elastic material, for example, plastic, which goes through the through hole of the modular element. This implementation of the double-side fixation tools ensures the capability of elastic axial bend of connected elements of double-side fixation tools that additionally improves the dynamic characteristics of the created models and constructions.
Wherein, the length of the connecting central core can be less than the thickness of the modular element, which causes elastic deformation of the contact surfaces with the bases of coaxial fastening elements with partly indentation into the surface of the modular elements. This ensures additional rigid resilient connection of the fastened modular elements, as there is no gap between protrusive parts of the mating elements.
Wherein, fastening elements of the double-side fixation tools can be connected with each other by bearing surfaces depending on the requirements to the construction kit.
Wherein, fastening elements or parts of fastening elements can be made of plastic or metal depending on the requirements to the construction kit.
Wherein, modular elements or parts of modular elements can be made of thick felt, felt, felt-cloth, rubber, PVC fabric, flexible polymer, PVC plastic, or a combination of these materials. The specified materials combine high flexibility and elasticity.
Wherein, the modular elements can be one-layer, two-layer or multilayer with 3-10 mm thickness of the modular elements. The specified thickness range of the modular elements ensures the flexible and elastic characteristics of the material.
Wherein the junction of the layers of modular elements can be carried out by means of the intermediate adhesive layer, or by thread sewing along the edges of the joined layers, depending on the characteristics of the used materials. Wherein, the thread sewing preferably to be used on the thick felt, felt or felt-cloth. Due to elastic characteristics of these materials the thread thickens the edge, which makes modular elements additionally resistant to the frontal pressure.
Wherein, the modular elements can include at least horizontally elongated, rectangular, triangular, circular plates, as well as the decorative circular plates.
Wherein, the horizontally elongated plates can be provided with at least two double-side fixation tools installed in longitudinal row.
Wherein, the rectangular and triangular plates can be provided with one double-side fixation tool at the corners.
Wherein, depending on the requirements to the construction kit, the above mentioned modular elements can have sharp and/or rounded ends.
Wherein, the circular plates can have different diameter and be equipped with the central double-side fixation tool.
Wherein, the decorative circular plates can have on the outer surface stylized eyes in the form of the transparent plastic hemisphere of various diameter, inside of which there are pupils of various diameter that easily move, and on the flip side there is the central outer or inner fastening element.

Embodiment of the invention

The claimed construction kit according to the variant shown in FIG. 1, is made of a set of flat modular elements in the shape of plates which have different form and size (1) -(15). Each modular element of the construction kit is made of flexible resilient material, preferably felt, and has two layers fixed in full perimeter by thread sewing. Modular elements of the construction kit are equipped with double-side fixation tools (16) which consist of the inner fastening element (17) which has a projection (18) and the outer fastening element (19), which has the surface of elastic coverage of the projection (20) (FIG. 2, 3), connected with each other by the elastic plastic core (21), that goes through a through hole of the modular element (1) to (15) (example - circular plate 7). When connecting modular elements to each other, or connecting parts of one modular element, fastening elements (17) and (19) form a detachable joint capable of holding together the mating surface portions or the whole mating modular element while providing the possibility of rotating the attachable portion or element by the above-described construction of the fastening elements (17), (19), and also the possibility of axial tilt of the connected sections due to the elasticity of the core (21). The set of modular elements according to FIG. 1 comprises the following parts: horizontally elongated plates (1)-(6) with the central row of double-side fixation tools (from 2 to 7) (16); circular plates (7)-(11) of different diameter with the central double-side fixation tool (16) (plate (7) can have a double-side fixation tool with similar fastening elements); triangular plates (12), with a single double-side fixation tool at each corner (16); rectangular (square) plates (13), with a single double-side fixation tool at each corner (16); decorative stylized circular plates with the central fixation tool (17) or (19) imitate eyes (14), (15).

Variants of embodiment of the invention

Modular elements of the construction kit, enable to create various spatial constructions and models.
For example, the assembling of the model «Horse» (Fig. 4) is performed in the following way.
Modular elements required:

horizontally elongated plates (5) - 1 unit;
horizontally elongated plates (6) - 10 units;
square plates (13) - 4 units;
circular plates (7) - 2 units;
decorative circular plates (15) - 2 units.

First we compose the head and the neck. To achieve that the 1^st and the 2^nd plates (6) (the head) are attached to the 1^st fastening elements of the 1^st plate (5) (the neck) on each side with their 1^st fastening elements and these plates are fastened together with the 2^nd fastening elements. Then both plates (7) are fastened on the 1^st fastening elements of the plates (6), after that the decorative plates (15) (the eyes) are fastened on them. Then the 1^st plate (5) is fastened with the 3^d fastening element on the 1^st fastening element of the 1^st square plate (13). On its 2^nd fastening element the 3^d plate (6) is fastened with the 1^st fastening element (the tail), and on the 3^d and the 4^th fastening elements the 4^th plate (6) is fastened with both elements. Then, by analogy with the 1^st plate (13) the 2^nd plate (13) is fastened on the front surface of the 1^st plate (5) and the 3^d and the 4^th plates (6). On the front surface of the 2^nd plate (13) the 5^th plate (6) is fastened to its 1^st and 2^nd elements. The 1^st fastening elements of the 6^th and the 7^th plates (6) (the legs) are fastened on the 3^d and the 4^th fastening elements. After that by analogy with the 2^nd plate (13) the 3^d plate (13) (the body) is fastened to the front surface of the 5^th, 6^th and 7^th plates (6). In the same way, on the opposite side of the 1^st plate (13) the 8^th, 9^th, 10^th plates (6) are fastened one by one to it, and the 4^th plate (13) is fastened to them.
As a result, we get the dynamic model «Horse», in which the limbs - neck, tail and legs - have the possibility of axial rotation with respect to the body, and the head - with respect to the neck. This enables more manipulations with the assembled model, changing the position of its limbs and fixing these changes on the playing surface, while the sufficient stability of the model is maintained.
A more complicated model «Tractor» (FIG. 5) with the sequence of the assembly is given.
Modular elements required:

horizontally elongated plates (1) - 1 unit;
horizontally elongated plates (3) - 3 units;
horizontally elongated plates (5) - 2 units;
horizontally elongated plates (6) - 5 units;
circular plates (7) - 9 units;
circular plates (8) - 4 units;
circular plates (11) - 8 units.

First the body is built. To achieve that, the 1^st, the 2^nd and the 3^d plates (6) are fastened layer-by-layer. The 1^st, the 2^nd and the 3^d plates (3) are alternately fastened lengthwise on the 3^d plate (6) with the 3^d and the 4^th fastening elements. Plate (1) is fastened to the upper plate (3) from the 1^st - 5^th fastening elements. Then the part of its surface with the 6^th and the 7^th fastening elements is folded so that the 7^th fastening element on the opposite side is connected through the 1^st circular plate (7) (with similar fastening elements) to the 5^th fastening element located on the inner surface of the 1^st plate (3). From the bottom of the 1^st plate (3), the 2^nd circular plate (7) is fastened to the 1^st fastening element. The 3^d plate (7) (the steering wheel) is fastened to the 2^nd fastening element of the plate (1), and to the 5^th fastening element - from the 4^th to the 9^th plates (7) respectively (the pipe). Next the wheels are assembled. Four circular plates (11) are used for every rear wheel, and two circular plates (8) for every front wheel. The plates are connected by the central fastening element. To form the axis of rotation of the front wheels, the 1^st plate (5) and the 4^th plate (6) are fastened together by an opposing fold, so that the fastening elements located on the outer surface of the 4^th plate (6) are connected to the last in row fastening elements on the inner surface of the 1^st plate (5). The fastening element in the center of the outer surface of the 1^st plate (5) is fastened to the 7^th fastening element of the outer surface of the plate (1), as a result, the center of the angular rotation of the axis of rotation of the front wheels is formed at the junction. Then the front wheels of the plates (8) are fastened with their central fastening elements to the edge fastening elements of the outer surface of the 1^st plate (5). In order to form the axis of rotation of the rear wheels, the 2^nd plate (5) is passed through the hole between the 2^nd and the 3^d fixing points of the fastening elements of the 1^st and the 2^nd plates (3), then the ends of the 2^nd plate (5) are bent and connected with the 5^th plate (6) by analogy with the central axis of rotation of the front wheels. At the final stage, the rear wheels of the plates (11) are attached with their central fastening elements to the edge fastening elements of the outer surface of the 2^nd plate (5).
The assembled construction clearly demonstrates the dynamic properties of the obtained model «Tractor». Both the wheels and the axis of rotation of the front wheels rotate, which enables game manipulations with the assembled model. At the same time, the wheels are stable, they do not bend under the body's weight, also due to their width, provided by the stated fixation tools.
The proposed building toy evokes increased fun and interest potential. The kit with the above mentioned properties enables to form children's skills for successful psychomotor development.
